Who We Are Contact Us Can I run the London Marathon for the Shark Trust? We’re always very grateful when people run marathons for us but unfortunately we’re unable to supply entrants with Golden Bond tickets. Charitable entries are extremely restricted and there’s currently a long list of charities waiting to receive golden bonds. If you’d like to run for the Shark Trust then please go through the usual ballot entry method. Or why not join us on one of our organised fundraising events?
